Given numbers are 686,261,516,902,470

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 686,261,516,902,470 is 1631952366660.

Find LCM of 686,261,516,902,470 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 343 x 87 x 86 x 451 x 235 = 1631952366660

Therefore, the lowest common multiple of 686,261,516,902,470 is 1631952366660.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

686 x 261 x 516 x 902 x 470 = 39166856799840

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

686 : 1, 2, 7, 14, 49, 98, 343, 686

261 : 1, 3, 9, 29, 87, 261

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

902 : 1, 2, 11, 22, 41, 82, 451, 902

470 : 1, 2, 5, 10, 47, 94, 235, 470

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,261,516,902,470, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

261:3x 3x 29

516:2x 2x 3x 43

902:2x 11x 41

470:2x 5x 47

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 3 = 24

Therefore, the value for common factors is 24.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 39166856799840/(1x24)

LCM = 39166856799840/24

LCM = 1631952366660

Thus, we can understand that the LCM of 686,261,516,902,470 is 1631952366660.
